Unless there are conflicting features, the following embodiments and features therein can be combined with each other.

Referring to FIG. 1, FIG. 1 is a schematic flow chart of one aerial vehicle control method according to an embodiment of the present disclosure. The methods according to the embodiments of the present disclosure may be applied to a variety of aerial vehicles such as multi-rotor aerial vehicles and fixed-wing aerial vehicles, wherein the multi-rotor aerial vehicles may further include various kinds of aerial vehicles such as four-rotor aerial vehicles, six-rotor aerial vehicles, eight-rotor aerial vehicles and other aerial vehicles with more or less rotors. Specifically, one method disclosed herein comprises:

S101: Upon receipt of an auto return instruction, control power output of an aerial vehicle in accordance with return point position information to make the aerial vehicle return to a return point. Specifically, a signal received by the aerial vehicle is detected, and if an auto return instruction is received, power output of the aerial vehicle is determined in accordance with a return point, to make the aerial vehicle fly towards the return point. In the process of auto return, the aerial vehicle flies towards the return point in accordance with pre-set attitude information, wherein the attitude information may include a flight altitude, a flight speed, a flight direction and so on.

The auto return instruction may be: a return instruction sent from a remote control end, a return instruction generated when a remote control signal from the remote control end is not received within a pre-set time range, or a return instruction generated when it is detected that a battery capacity value reaches a return required value and the aerial vehicle has to return.

The return point position information may be: user-configured, or automatically-set (for example, an automatically-set take-off point) return point GPS (Global Positioning System) coordinates, and may also be information about a relative distance between the return point and a current position, direction information, or other information.

S102: In the process of return, if a flight control instruction is detected, adjust the power output of the aerial vehicle in accordance with the flight control instruction.

The power assembly may include an electronic speed adjustor, a motor, a propeller and so on.

The detection action may be completed through a signal receiving element, when it is detected that strength of the signal received is greater than a pre-set threshold, the signal is considered as a flight control instruction and the flight control instruction is executed, otherwise, the signal detected is ignored.

With the aerial vehicle control methods according to the embodiments of the present disclosure, a flight control instruction can be received in the process of return, which makes the aerial vehicle operation more flexible and can meet more demands of users.

Referring to FIG. 2, FIG. 2 illustrates another aerial vehicle control method according to another embodiment of the present disclosure. Specifically, the method comprises:

S201: Upon receipt of an auto return instruction, control power output of an aerial vehicle in accordance with return point position information to make the aerial vehicle return to a return point.

Specifically, a signal received by the aerial vehicle is detected, and if an auto return instruction is received, power output of the aerial vehicle is determined in accordance with a return point, and a corresponding control instruction is generated and sent to a power assembly, to make the aerial vehicle fly towards the return point. In the process of auto return, the aerial vehicle flies towards the return point in accordance with pre-set attitude information, wherein the attitude information may include a flight altitude, a flight speed and so on.

The return point position information may include a GPS signal of the return point, and may also be information about a relative distance between the return point and a current position, a direction and other information.

S202: In the process of return, detect whether or not a flight control instruction for the aerial vehicle is received.

In the process of return, whether or not a flight control instruction for the aerial vehicle is received is detected. The flight control instruction may be an operation instruction sent from a user control end to the aerial vehicle, used for controlling power output of the aerial vehicle, so as to achieve a change of attitude of the aerial vehicle to complete a user-expected action.

The detection process may be completed through a signal receiving element, if the strength of the signal received by the signal receiving element is greater than a pre-set threshold, the signal is considered as a flight control instruction, otherwise, the signal is considered as a noise signal and is ignored.

S203: If the flight control instruction for the aerial vehicle is received, adjust the power output of the aerial vehicle in accordance with the return point position information and the flight control instruction.

Specifically, in the process of return of the aerial vehicle, a return instruction may be generated in accordance with the return point position information, for example, GPS information of the return point and so on, the return instruction calculates a specific control instruction for the power assembly through a pre-set algorithm, that is, power output of each power assembly to perform return is calculated, and the control instruction is sent to the power assembly.

When the flight control instruction is received, a return instruction generated in accordance with the return point position information and the fight control instruction may be superimposed. The power output of the aerial vehicle may be controlled in accordance with the superimposed instruction.

At this point, the aerial vehicle superimposes the return instruction on the flight control instruction, that is, on the basis of the power output of each power assembly calculated by the return instruction, the power output of each power assembly to execute the flight control instruction is superimposed thereon, and new power output of each power assembly is calculated through a pre-set algorithm, so as to execute the flight control instruction as the same time when the return instruction is executed.

In the above process, when the aerial vehicle executes the flight control instruction, parameters of the return instruction are also taken into account, and a control instruction is obtained by integrating the flight control instruction and the parameter of the return instruction, to control power output of the aerial vehicle.

In addition, when the flight control instruction is received, it is also feasible to generate a control instruction by integrating the return point position information and the flight control instruction, that is, power output of each power assembly of the aerial vehicle is calculated and calculated through a pre-set algorithm in accordance with the return point position information and the flight control instruction.

In the above process, when the aerial vehicle executes the flight control instruction, parameters of the return point position information are also taken into account, and a control instruction is obtained by integrating the flight control instruction and the parameter of the return point position information, to control power output of the aerial vehicle.

Return of the aerial vehicle is generally rectilinear flight, that is, a relationship between a current position of the aerial vehicle and the return point is calculated to obtain a flight path, and the aerial vehicle flies to a position above the GPS position of the return point, and lands and goes back to the return point. If there is an obstacle between the current position of the aerial vehicle and the return point, the user can perform an operation to send an operation instruction to the aerial vehicle to instruct it to bypass the obstacle. A flight trajectory of the aerial vehicle is determined by a control instruction, wherein the control instruction is obtained by integrated calculation of the return instruction and the flight control instruction, or obtained by integrated calculation of information of the return point and the flight control instruction. Hence, the flight trajectory is between a return trajectory and a predetermined trajectory of the flight control instruction.

The user can send multiple flight control instructions, to ensure that the aerial vehicle bypasses the obstacle. Further, the user can also send the flight control instruction to make the aerial vehicle complete other actions in the process of return, for example, the aerial vehicle flies to a particular position, including flying at a particular altitude or flying a particular distance to shoot a picture and so on.

If the flight control signal is not received, the aerial vehicle continues to return.

In the embodiments of the present disclosure, it is possible to operate the aerial vehicle in the process of return, which enhances security and operation flexibility of the aerial vehicle.

Referring to FIG. 3, FIG. 3 illustrates a further aerial vehicle control method according to another embodiment of the present disclosure, and specifically, the method comprises:

S301: Upon receipt of an auto return instruction, control power output of an aerial vehicle in accordance with return point position information to make the aerial vehicle return to a return point.

S302: In the process of return, detect whether or not a flight control instruction for the aerial vehicle is received.

S303: If the flight control instruction for the aerial vehicle is not received, continue to control the power output of the aerial vehicle in accordance with the return point position information to make the aerial vehicle return to the return point.

S304: If the flight control instruction for the aerial vehicle is received, suspend the control over the power output of the aerial vehicle in accordance with the return point position information, and adjust the power output of the aerial vehicle in accordance with the flight control instruction.

When the flight control instruction is received, it is feasible to interrupt the return, that is, interrupt the control over the power output of the aerial vehicle in accordance with the return point position information, and calculate and set power output of each power assembly of the aerial vehicle in accordance with the flight control instruction and through a pre-set algorithm, to complete an action specified by the flight control instruction.

In the above process, the aerial vehicle flies in accordance with a trajectory predetermined by the flight control instruction.

S305: After adjustment on the power output of the aerial vehicle in accordance with the flight control instruction is completed, turn on the control over the power output of the aerial vehicle in accordance with the return point position information.

After the action specified by the flight control instruction is completed, if the signal receiving element does not detect receipt of a new control flight instruction, it is feasible to trigger a control system of the aerial vehicle to make it continue to return, that is, turning on the control over the power output of the aerial vehicle in accordance with the return point position information. Further, when the adjustment of the flight control instruction on the power output of the aerial vehicle is completed, it is feasible to turn on the control over the power output of the aerial vehicle in accordance with the return point position information after a pre-set time, that is, the return is continued, and step S303 is performed.

In this embodiment, after it is detected in the process of return that the flight control instruction for the aerial vehicle is received, the aerial vehicle may also execute the flight control instruction, exit from the return state and no longer continue to return, and all flight and actions thereafter are decided in accordance with the user's operation and/or environment parameters of the aerial vehicle. That is, if step S304 is performed, step S305 is not performed, and the aerial vehicle may not to go back to perform step S303.

With the embodiments of the present disclosure, it is possible to operate the aerial vehicle in the process of return, which enhances security and operation flexibility of the aerial vehicle.

The return control module 1 detects a signal received by the aerial vehicle, and determines power output of the aerial vehicle in accordance with a return point if an auto return instruction is received, to make the aerial vehicle fly towards the return point. In the process of auto return, the aerial vehicle flies towards the return point in accordance with pre-set attitude information, wherein the attitude information may include a flight altitude, a flight speed, a flight direction and so on.

In this embodiment, the control adjustment module 2 comprises:

a detection unit 21 used for, in the process of return, detecting whether or not a flight control instruction for the aerial vehicle is received; and

a power adjustment unit 22 used for, if the detection unit detects that the flight control instruction for the aerial vehicle is received, adjusting the power output of the aerial vehicle in accordance with the return point position information and the flight control instruction.

In the process of return, the detection unit 21 detects whether or not the flight control instruction for the aerial vehicle is received. The flight control instruction may be an operation instruction sent by a user control end, which is used for controlling power output of the aerial vehicle through the operation instruction, so as to achieve a change of attitude of the aerial vehicle to complete a user-expected action.

In the detection process, if the strength of a signal received by a signal receiving element is greater than a pre-set threshold, the signal is considered as a flight control instruction, otherwise, the signal is considered as a noise signal and is ignored.

If the flight control instruction for the aerial vehicle is received, the power adjustment unit 22 may superimpose a return instruction generated in accordance with the return point position information and the fight control instruction, and control the power output of the aerial vehicle in accordance with the superimposed instruction.

At this point, the power adjustment unit 22 may superimpose the return instruction and the flight control instruction, that is, on the basis of the power output of each power assembly calculated by the return instruction, the power output of each power assembly when the flight control instruction is executed is superimposed thereon, and new power output of each power assembly is set through a pre-set algorithm, so as to execute the flight control instruction at the same time when the return instruction is executed.

In the process, when the aerial vehicle executes the flight control instruction, the power adjustment unit 22 also takes parameters of the return instruction into account, and obtains a control instruction by integrating the flight control instruction and the parameters of the return instruction, to control power output of the aerial vehicle.

In addition, when the flight control instruction is received, the power adjustment unit 22 may also generate a control instruction by integrating the return point position information and the flight control instruction, that is, power output of each power assembly of the aerial vehicle is calculated and set through a pre-set algorithm in accordance with the return point position information and the flight control instruction.

In the process, when the aerial vehicle executes the flight control instruction, the power adjustment unit 22 also takes parameters of the return point position information into account, and obtains a control instruction by integrating the flight control instruction and the parameters of the return point position information, to control power output of the aerial vehicle.

A flight trajectory of the aerial vehicle is determined by a control instruction, which is obtained by integrated calculation of the return instruction and the flight control instruction or obtained by integrated calculation of information of the return point and the flight control instruction. Hence, the flight trajectory is between a return trajectory and a predetermined trajectory of the flight control instruction.

The user can send multiple flight control instruction, to ensure that the aerial vehicle bypasses the obstacle. Further, the user can also send the flight control instruction to make the aerial vehicle complete other actions in the process of return, for example, the aerial vehicle flies to a particular position, including flying at a particular altitude or flying a particular distance to shoot a picture and so on.

If the flight control instruction is not received, the adjustment unit 22 does not adjust the power output of the aerial vehicle, and the aerial vehicle continues to return.

In addition, when the flight control instruction is received, the adjustment unit 22 may also interrupt the return, that is, interrupt the control over the power output of the aerial vehicle in accordance with the return point position information, and calculate and set power output of each power assembly of the aerial vehicle in accordance with the flight control instruction through a pre-set algorithm, to complete an action specified by the flight control instruction.

In the above process, the aerial vehicle flies in accordance with a trajectory predetermined by the flight control instruction.

After the action specified by the flight control instruction is completed, if the detection unit 21 does not detect receipt of a new control flight instruction, the power adjustment unit 22 adjusts the aerial vehicle to restore the return state in accordance with the return point position information, that is, turning on the control over the power output of the aerial vehicle in accordance with the return point position information. Further, once the adjustment of the flight control instruction on the power output of the aerial vehicle is completed, it is feasible to turn on the control over the power output of the aerial vehicle in accordance with the return point position information after a pre-set time.

In addition, after it is detected in the process of return that the flight control instruction for the aerial vehicle is received, the aerial vehicle may execute the flight control instruction and exit from the return state. That is, the power adjustment unit 22 sets the power output of the aerial vehicle in accordance with the flight control instruction, the return is no longer continued, and all flight and actions thereafter are determined in accordance with the user's operation and/or environment parameters of the aerial vehicle.

A flight trajectory of the aerial vehicle is determined by a control instruction, wherein the control instruction is obtained by integrated calculation of the return instruction and the flight control instruction or obtained by integrated calculation of information of the return point and the flight control instruction. Hence, the flight trajectory is between a return trajectory and a predetermined trajectory of the flight control instruction.
